NEW BEDFORD — A New Bedford man was arrested Monday on murder charges connected with a 2005 killing in the city's South End.

Fagbemi Miranda, 31, is accused of collaborating with his brother, Wayne, to shoot and kill Christopher Barros in October 2005.

Wayne Miranda was arrested shortly after the shooting and charged with murder, according to Gregg Miliote, a spokesman for District Attorney Sam Sutter. He is being held without bail while awaiting trial.

Fagbemi was indicted by a Bristol County Grand Jury Friday, and New Bedford police tracked him to his home at 439 Purchase St. Monday afternoon, according to Mr. Miliote.

Mr. Miranda tried to fight off two police officers who were taking him into custody, according to Lt. Jeffrey Silva, New Bedford police spokesman. During the struggle, Mr. Miranda's pit bull burst into the room and leapt onto an officer; the pit bull was shot and killed, Lt. Silva said.

The 25-year-old Mr. Barros was shot in the city's South Central neighborhood on Oct. 10, 2005, after what witnesses described as an argument between Mr. Barros and Mr. Miranda.

As the fight between the two men escalated, Wayne Miranda allegedly emerged from his home at 439 Purchase St. with a gun and, along with two or three other men, chased Mr. Barros into a nearby driveway and allegedly shot him twice.

At the time of the shooting, Fagbemi Miranda gave police a dramatically different version of the story, saying he had been chased by a masked man with a gun who had fired two shots at him before he was able to escape.

Wayne, a Monte Park gang member with a long arrest record, had been arrested in 2003 on a gun charge for which then-City Councilor Joseph Fortes was a key witness.

A police report at the time of Wayne's arrest on the gun charge stated Mr. Fortes told police he saw Wayne with a gun in the city's South Central neighborhood. According to police, Mr. Fortes drove by the officers arresting Wayne and identified him over the phone to detectives as the man he had seen with a gun.

During Mr. Fortes' testimony at the trial, however, he said he never saw Wayne with a gun. He just relayed reports of a gunman to police through then-Mayor Frederick M. Kalisz Jr.

At a City Council meeting after Mr. Barros' death, then-District Attorney Paul Walsh lashed out at Mr. Fortes, saying the shooting could have been prevented if Wayne had been successfully prosecuted on the 2003 gun charge.

Fagbemi Miranda is charged with murder, unlawful carrying of a firearm without a license and assault and battery with a dangerous weapon, according to Mr. Miliote. He will be arraigned in New Bedford Superior Court today.
